RTNOU Project

"Real-Time Network Optimisation Utilities."

Based on the results of my Phd dissertation I have implemented a set of utility and optimization algorithms. You can download the C++ source code of these functions and a sample program that works with them.

RTNOU Library

    This library is written in standard C++ and has two implementation files and its associated header files. The core of the library is in the RTNOULib files. These functions includes procedures to obtain:

    The functions are commented in the source. The description of these algorithms can be found in these references.

    The other files, CAdmissionTest, contains a set of C++ classes that implement several admission test control for a network network given a set of flow loads.

RTNOU Program

    RTNOU is a Win32 program developed with Visual C++. It provides a simple and graphical user interface to test all the algorithms of the RTNOU Library. As a research program it is in permanent construction, so it is easy that you find bugs. The last version is the 4.2 and has a new User's Manual.
    Main characteristics:   You can use this program with the following traffic traces:     If you have any question or find any problem in the program, do not hesitate to send me an email.
